Dome Light Help

Can’t tell how this works. Can someone explain. Not sure how the middle part of the light gets power. Don’t have either front or rear dome light when doors open. Map lights work. Checked fuses and bulbs. They are good. Door ajar light works when door is open also.

Been a while since I looked at this circuit, but the dome light gets power from the keep alive relay in the instrument cluster
Does your radio and windows work for several seconds after the key is off, but stop when the door is opened?

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.
